Your imagery is strong. It’s easy to imagine the pair, given the character constraint. Maybe, in further ficlets, you might want to describe her more.
If I may offer some editing suggestions: - best friends - Your first sentence runs on. Make “we had been best friends…” a complete sentence. Make “it was she who…” a complete sentence also. - Capitalize your I’s. - best friend - put a comma after ‘secrets and stories’ - end the sentence after ‘down’. New sentence with ‘we had…’ - each others ; put an apostrophe after others - apostrophe for that’s, since it’s a contraction - change the comma after ‘already has’ to a semi-colon. You’ve got two independent clauses there. - “I stare out at the horizon, with the sun beaming and the birds singing; if only she was here right now.” - “She always loved the summer—getting a tan outside and reading magazines all day, it was her idyllic weather. But she wasn’t here, and now I will never see her again…”
